These rotors and brakes are 12 years old and that is and was a stated fact.
Also I just got off summit racings website part # ,140-11020 these brakes are 100% identical visually, only three small differences they state 11 inch diameter. Mine are 10 3/4 , they stated rotor thickness .810 mine are .806, they state the rotors are 4.5 and 4 3/4 bc .mine are 4.0 4.5 take a look, compare and decide
